任意自旋无质量超多重态和高自旋超场立方相互作用中的守恒高自旋超流

Conserved higher spin supercurrents for arbitrary spin massless supermultiplets and higher spin superfield cubic interactions

I. L. Buchbinder, S. James Gates, Konstantinos Koutrolikos

摘要:

给出了由任意自旋的$4D,\mathcal{N}=1$无质量超多重态构成的高自旋守恒超流的显式超空间结构。这些超电流是规范不变的,并产生了一个大类的立方相互作用之间的无质量超多重带超自旋$Y_1=s_1+1/2$和两个无质量超多重带任意超自旋$Y_2$。这些相互作用仅可能用于$s_1\geq 2Y_2$。在相等时,超电流获得其最简单的形式,并定义了线性化的贝尔-罗宾逊张量的超对称、更高自旋的扩展。

英文摘要:

We give an explicit superspace construction of higher spin conserved supercurrents built out of $4D,\mathcal{N}=1$ massless supermultiplets of arbitrary spin. These supercurrents are gauge invariant and generate a large class of cubic interactions between a massless supermultiplet with superspin $Y_1=s_1+1/2$ and two massless supermultiplets of arbitrary superspin $Y_2$. These interactions are possible only for $s_1\geq 2Y_2$. At the equality, the supercurrent acquires its simplest form and defines the supersymmetric, higher spin extension of the linearized Bel-Robinson tensor.
